The DG9431 is a single-pole/double-throw monolithic CMOS
analog device designed for high performance switching of
analog signals. Combining low power, high speed (t
t
physical size (TSOP-6), the DG9431 is ideal for portable and
battery powered applications requiring high performance and
efficient use of board space.

The DG9431 is built on Vishay Siliconix’s low voltage BCD-15
process. Minimum ESD protection, per Method 3015.7, is
2000 V. An epitaxial layer prevents latchup. Break-before
-make is guaranteed for DG9431.
Each switch conducts equally well in both directions when on,
and blocks up to the power supply level when off.
